ZClaims. (Olsen-133) iTherinvention relates :to animproved table v-01the type having a rotatable or rotary center section-. in-its top, theprimary object of. the inventtion *beingto providev .a more practicaland serviceabletable of this character which is especially -suitable foruse [in restaurants and'othercom- ,mercia'l establishments; such asmanufacturin :or assembling plants.

- Other objects and advantages of the invention wwill appear in furtherdetail as thespecifi-cation :proceeds.

that each of the supporting arms 8 is a lightweight butlrigid andfirm-supporting structure 'for thering shaped: table top+section Ill.The inclusion of several .such supporting arms secured In ordertofacilitate ready comprehension of i this invention and 1a properappreciation of :the salient features thereof, a specific embodiment.iof' the invention is illustrated" in the accompanyr'ing drawings:forming parthereof and .in which:

Figure 1 is a perspective view; :Fignre :2 is a horizontal section takenon line 22 in Figure 1;

Figure 3 is .airagme'ntaryitransverse verticalsection .takenonline 3-3in Figure .2.

I In the views, the same reference numerals indicate the same or likeparts.

Referring in detail to the "drawings, the illustrated table, generallydesignated 4, comprises a v.group ofzfeet 5 securedtogether inacruciform idesignrto thelower .endsfi iofpa vertical cylindricalpedestal .1, about whose upper part are secured :a groupofcircumferentially spaced,- radially outwardlyand upwardly-extendingsupporting arms :generally indicated at 8, .8. The supporting arms18;.each consist of a...radiallyextending horizontal strip xof "metalbenthdownwardly to form, a de- .x=pending. lug 7.] ll, at the. inner endthereof, secured Ifby a pair ot screwsll toithe pedestal 7|, :the outerpart of the arm 9 being curved upwardly at 2 and formed at its outer endwith a radially outwardly extending attachment lug l3, secured by screws4 to the underside of a stationary annular table top section I5. Thesection I5 is enclosed by a covering including a channel It of plasticor metal engaging over its outer peripheral edge." A diagonal brace l8of metal strip has its lower, and radially inward end secured, asindicated at IT, as by welding or brazing, to the inward end of thesupporting arm portion 9 and has its radially outward or upper endsimilarly secured, as indicated at l9, to the upper and outward end ofthe arm portion I2. In addition, a horizontal brace 20, also formed ofmetal strip, is bent. downwardly at the inner end thereof to form anattachment lug 2| which is secured by pairvotkiscrews 22 to the upperpart of the pedestal "I and has its outer end welded or brazediasiindicated at 23', to an intermediate portionofi'the diagonal bracel8. The result is to the pedestal and-tothe undersideaof a. the

stationary table top section I15. at equidistantly spaced,.points.adequately supports the same and provides at the .samertime free accessto the underside of the table top. and. the pedestal. for

cleaning or other purposes.

The annular stationary section 1 I5 has .a .cen-

tralieircular opening 24, and-the inner peripheral "edge ofth8-1SBCtiOn-|-5 isprov-ided with arelnforcing-channel .25 to present aperfectly icircu- ;1a1 ,'.-sm0oth,-.and' reinforced edge. Cooperatinwith the section IE to complete the table top. is

.a circular centertable .top section 6, which occupies the opening24,..andis provided .cn..its

peripheral-edge with a finishingandreenforcin channel 21. The rotarysection 26 is supported in aflush i relation with the top of thestationary section IS. TO the center of the underside of the rotarysection IEis secured.ametaldisc 28 Jay inea-nsnof. a; group of screws.29 and the disc 25,

has. thereintan lar-cuatefinger hole or slot .30, intowhich thelfingers.can he, thrust to facilitate handling-the rotary section 25, from belowwhen required. To the-center oftheunderside of the :disc 23 isbrazed orwelded a vertical axis nut 3 :The upper end-32 zof the pedestal isformed with an upwardly openingcylindrical recess 33 in which fitted anlupwardly opening metal ;-.cylinder 3-4 terminating flush with the upperend .of the pedestaland having aclosed bottom .35.

Within thehollow cylinder .34 and resting upon the bottom 35. thereof isa ball thrust bracing 38 which includes a lower ball race 36 which iswedged in the cylinder by means of a shim 31, and has an upper annularball race 41. Within the upper end of the hollow cylinder 34 isforcefitted a ball bearing 39 having an outer race 40 and an annularinner race 4|. Into the above mentioned nut 3| is screwed the upperthreaded end of a reduced portion 42 of a spindle 43' which is axiallypositioned in the cylinder 34. The reduced portion 42 extends throughthe opening of the annular inner race 4| and defines an upper shoulder44 which supportably engages the underside of the inner race 4|. At itslower end the spindle 43 is provided with a reduced portion 45 whichextends through the opening of the upper race 41 and defines a lowershoulder 46 which rests upon the upper ball race 41 of the thrustbearing 38, the upper race 41 being arranged so that the thrust bearing38 supports the combined weight of the spindle 43 and the rotary tabletop section 26, while the upper ball bearing 38 holds the rotary section26 centered in the table top opening 24 and eliminates transversestrains and displacements thereof relative to the pedestal I and thestationary table top sesction l 5 and allows free rotation of the rotarysection 26 within the opening 24 in the stationary section IS. Theannular stationary section l5 may be covered with coating material 48,and similarly the rotary section 26 may be provided with surfacingmaterial 49, the two sections being flush in such a manner that articlescan be freely slid thereon across the table top in any direction.

The arrangement is such that if the table is used in a restaurant, forexample, various containers of condiments, sauces, and supply dishesplaced upon the rotary section 26 will be readily accessible to agroupof persons seated around the table, since the rotary section can beeasily rotated to bring any of the various containers or dishes withinreach of any of the group. While one of the group is being served from amain dish, others of the group can momentarily use the containers ordishes from the rotary section 26, and after replacing the containers ordishes thereon the rotary section 26 can be retated in step-by-stepfashion to make the container available in succession to the various members of the group. The'table can also be used for assembling aparatus byhaving a group of assemblers around the table with a supply of parts onthe rotary section 26, so that the rotary section 26 can be rotatedstep-by-step to con: front each successive assembler in turn with theproper parts.

Manifestly, variations may be resorted to and parts and features may bemodified or used without others within the scope of the appended claims.

Having now fully described my invention, I

claim:

1. In a table, a pedestal formed in its upper end with a recess, ahollow cylinder'fitting said recess. said cylinder having an open upperend upper end portion extending upwardly through the opening in saidannular bearing, said reduced upper end portion defining an uppershoulder on said spindle bearing against the undersideof said annularbearing, a circular rotary table top section fixed centrally upon saidspindle above said upper annular bearing, and an annular stationarytable top section fixedly mounted on said pedestal and surrounding saidrotary table top section.

2. In a table, a. pedestal formed in its upper end with a recess, ahollow cylinder fitting said recess, said cylinder having an open upperend and a closed bottom, a lower ball thrust bearing supported on thebottom of said cylinder having an annular upper race, a spindlepositioned axially in said cylinder having a reduced lower end portionextending downwardly through the opening of said annular upper race,said reduced lower end portion defining a lower shoulder on said"spindle supportably resting upon said upper race, an upper annularbearing fixed in the upper end of said cylinder, said spindle having areduced upper end portion extending upwardly through the opening in saidannular bearing, said reduced upper end portion defining an uppershoulder on said spindle bearing against the underside of said annularbearing, a circular'rotary table top section fixed centrally upon saidspindle above said upper annular bearing, and an annular stationarytable top section fixedly mounted on said pedestal and surrounding saidrotary table top section, said reduced upper end portion being threadedand said rotary table top section having a nut secured to its undersideinto which the threaded reduced upper end portion of the spindle isthreaded.
